A fire bucket is a bucket filled with water or sand which is used to prevent or extinguish fires. They are usually painted bright red and have the word fire stencilled on them. Often they have a convex, protruding bottom, rendering them useless for other purposes, thus reducing the potential for theft or misuse. Fire buckets are a low-technology method of fighting small fires. The main advantages of fire buckets are that they are cheap, reliable easy to use and can be quickly refilled and reinstated.
